8GB of RAM is severe overkill. WinXP can't even address a full 4GB RAM.

The problem is that i want to keep the radio signal from the antenna!
could i keep the head unit to keep the best radio signal?
Yes.

can i plug the remote from my head unit ...to the amplifier...and plug the amplifier to my sound card ...
If you do that, you'll be bypassing the headunit.
You want Sound Card -> Headunit AUX IN -> Amplifier(s)

could i conect the radio to my sound car integrated in the pc(the green slot) and conect the sound card usb via the usb port to my amplifiers?
You already asked that. Yes, you could, but you would be bypassing the headunit, and losing all of its functionality, including the radio.
SOUND CARD -> HEADUNIT AUX IN -> AMPLIFIER(S)

i have a sound car audigy usb....it is suposed to my 7.1 but i dont see 8 ports.... i'm i suposed to use 'y' rca?
It doesn't matter for a car environment. You're not going to be using 7.1 from the sound card.
You'll use simple stereo (left & right channels) into the headunit.
